This paper explores the principle of the technology of frequency control of motor speed for condensate pumps,and conducts the analyses of frequency conversion renovation experiments and energy conservation econo-my. After the frequency conversion renovation of the pumps,the unit can save about 51％ of electricity at low loads and 13％ ～15％ at high loads. The electricity-saving effect is remarkable,saving costs for enterprises.
